ABSTRACT:
An image display system is provided in which an image to be displayed is subdivided into a plurality of images. The plurality of images are displayed on a plurality of display devices. An image is converted to a high definition television signal, and then converted to a plurality of signals compatible with standard television systems. Since the image is subdivided electronically, mismatching between screens is avoided. Further, when the input image to be displayed has an aspect ratio larger or smaller than that of the high definition television system, the displayed image is appropriately shifted, thus eliminating hardware and reducing the system cost.
